Improvement in axle-boxes



UNITED STATES ALBERT GOODYEAR, 2D, OF HAMDEN, CONNECTICUT.

IMPROVEMENT IN AXLE-BOXES.

Specification forming part of Letters Patent No. 116,702, dated July 4, 1871.

To all whom it may concern.-

Be it known that I, ALBERT GOODYEAR, 2d, of Hamden, in the county of New Haven and State of Connecticut, have invented anew Improvement in Axle-Boxes 5 and I do hereby declare the following, when taken in connection with the accompanyin g drawing and the letters ofl reference marked thereon, to be a full, clear, and exact description oi' the same, and which said drawing constitutes part of this specification, and represents, in-

Figure 1, a side view of the box complete; Fig. 2, a longitudinal central section ofthe same 5 and in Figs. 3 and 4, the two parts detached preparatory to welding.

This invention relates to an improvement in axle-boxes for carriage-wheels, designed principally for that class of wheels in which the box must necessarilybe very light; and it consists in a steel tube combined with a malleable-iron neck, the two parts heated, and while in a heated state Welded together to forni a perfect whole.

A is the tube, formed from sheet-steel or other suitable metal, lapped and welded. B is the neck, formed from malleable iron by casting the saine in the usual manner for this class of castings, and constructed with one or more projections, C, to prevent the turning ofthe box in the hub. The tube is made slightly tapering at the neck end,

as seen in Fig. 4, and the interior of the neck of similar form, as seen in Fig. 3. Both parts are heated to a welding-heat, the tube placed upon a rod closely litting the interior, and the neck set thereon, the two parts being held in such position tha-t aI great and sudden pressure may be brought to bear upon the neck, forcing it onto the tube, and in the highly-heated state of the metal causing the two to marry or unite together and become practically one and the same piece.

The advantages of the steel box over the coinmon cast-iron boX aretoo apparent to require deiining.

The box thus constructed is bored out and finished in the usual ina-nner, and, while it may be made extremely light, yet possesses sufficient strength for all practical purposes.

I cla-ini as my invention- As a new article of manufacture, the hereindescribed axle-box, consisting of the wroughtmetal tube A and malleableiron neck B, the two united by the process of welding, substantially in the manner described.
